I think it would be useful to get a big list of configurator printouts, then add all the modifiers to a database so future GB organisers can know what the most common setup will be.
This is what I did, by hand earlier this week for the first 22 layouts I could find with Google. I had excluded the layer keys as I didn't see a good way to legend them, but Squarefrog and I were discussing over on DT that maybe just a LAYER key would work and give the most flexibility.
In any case, here's the sample data (PDF, excel available if you want). An automatic scraper would be better, and probably give more accurate results.
Do you guys think we can get a full poll organized before next week?
Otherwise, considering the set already does match reasonably well, I'd suggest we either drop the 1.5x /? key for a LAYER key, or add two LAYER keys. If all of us ergodoxers are gonna get blanks as well, then we can replace the SPACE with either an FN or a LAYER as well. We should be able to decide that pretty quickly.
EDIT: just wanted to add, I'd really like to see legend on these caps, even if they're only a partial match. Legended ergodox keys don't seem to crop up often.
